Hey guys,
I am going to tell you how to make note pad in Python Tkinter
Here i have implemented File and Edit options.
Here i have used flag option to check whether file is changed or not.
Code:
import Tix
import tkFileDialog
import tkMessageBox
import tkColorChooser
from FontChooser import *
class App:
def callback():
print "click!"
def onClose(self):
# check if saving
if(self.flag==1):
self.flag=0;
self.root.destroy()
else:
f=Tk()
f.minsize(width=450,height=50)
f.title("Please save your work or quit")
label = Label(f, text="DO you want to make any changes to current file?")
label.pack()
#b = Button(f, text="OK", command=callback)
#b.pack()
myYesButton = Button(f,text='Yes', command=self.doSaveAs)
myNoButton = Button(f,text='No', command=self.doQuit)
myYesButton.pack()
myNoButton.pack()
f.mainloop()
#myNoButton = Button(frame,text='Cancel', command=self.doQuit(self))
def __init__(self):
# Set up the screen, the title, and the size.
self.fileOp=0
self.root = Tk()
self.flag=0
self.root.title("Untitled")
self.root.minsize(width=500,height=400)
self.curr_var = StringVar(value='-:-')
self.root.protocol('WM_DELETE_WINDOW', self.onClose)
# Set up basic Menu
menubar = Menu(self.root)
# searching
# Set up a separate menu that is a child of the main menu
filemenu = Menu(menubar,tearoff=0)
editMenu = Menu(menubar,tearoff=0)
filemenu.add_command(label="New File", command=self.doNew,
accelerator="Ctrl+N")
# Try out openDialog
filemenu.add_command(label="Open", command=self.doOpen,
accelerator="Ctrl+O")
# Try out the save
filemenu.add_command(label="Save", command=self.doSave,
accelerator="Ctrl+Shift+S")
# Try out the saveAsDialog
filemenu.add_command(label="Save As", command=self.doSaveAs,
accelerator="Ctrl+Shift+S")
# Try out the Quit
filemenu.add_command(label="Quit", command=self.doQuit,
accelerator="Ctrl+Q")
menubar.add_cascade(label="File", menu=filemenu)
# Setting up edit menu
editMenu.add_command(label="Undo",command=self.doUndo, accelerator="Ctrl+z")
# Try out Redo
editMenu.add_command(label="Redo",command=self.doRedo, accelerator="Shift+Ctrl+z")
# Try out cut

# Try out Select all
editMenu.add_command(label="Select All",command=self.doSelectAll, accelerator="Ctrl+A")
# Try out delete
editMenu.add_command(label="delete",command=self.doDelete, accelerator="Del")
# Try out color chooser
editMenu.add_command(label="Color chooser",command=self.colorChooser)
#Try out Font Chooser
editMenu.add_command(label="Font chooser",command=self.fontChooser)
menubar.add_cascade(label="Edit", menu=editMenu)
self.root.config(menu=menubar)
